Senior Hardware Reliability Test Engineer – Electrical Systems & Power Electronics at Cerebras · LumiJobs

Responsibilities

Design, assemble, and troubleshoot custom electrical test jigs, fixtures, interface boards, load circuits, and wiring harnesses for power electronics and system reliability testing.
Work directly with the Systems team to establish representative workloads, power sequencing, electrical interfaces, operating limits, and monitoring requirements.
Translate product requirements and reliability risks into test plans with defined stress conditions, sample sizes, durations, measurements, and acceptance criteria.
Build automated test setups integrating programmable power supplies, electronic loads, switching hardware, sensors, and data acquisition equipment.
Develop Python or equivalent software for instrument control, test sequencing, continuous monitoring, fault capture, and analysis.
Execute accelerated life testing, burn-in, powered temperature cycling, power/load cycling, and biased temperature/humidity testing based on the hardware and failure mechanisms being evaluated.
Establish electrical baselines and monitor changes before, during, and after stress. Measurements may include efficiency, regulation, ripple and noise, transient response, startup/shutdown behavior, protection functions, and thermal derating.
Investigate electrical failures using schematics, PCB layouts, component datasheets, and bench measurements to isolate shorts, opens, leakage, intermittent behavior, and performance degradation.
Reproduce system-level anomalies in controlled experiments with the Systems team and correlate electrical results with physical failure-analysis findings.
Use DOE, statistical reliability analysis, and physics-of-failure methods to assess degradation, compare design alternatives, and evaluate component or process changes.
Partner with Design, Failure Analysis, Mechanical/Thermal Engineering, Quality, Manufacturing, and suppliers to validate corrective actions and communicate reliability risks.
Maintain calibrated, repeatable test setups with appropriate electrical protection and interlocks.
